Repellent of the stray animals

Abstract

Abstract The ultrasound frequencies are still receiving a lot of interest by scientists and researchers. It is used in many areas of life, especially medicine, where it was used in the diagnostic and therapeutic side. And also, it is used in the field of industry and other fields of life. The ultrasound frequencies cannot be heard by humans, but most animals hear them, especially dogs. Ultrasonic frequencies cause inconvenience in dogs. In this study, a modified device was made and used to eliminate dogs from cities and neighborhoods. The modification was of some electronic circuits in the available devices (available in the local markets) to generate ultrasound frequencies. The modified device was carried and switched off-on in multiple areas around cities and countryside and applied near groups of dogs in order to see the influence of the switch on (producing ultrasound frequencies) of the device on animals. The use of the new technique results in expel animals and dogs away from the areas of wave centers. Therefore, this technique can be used against predators such as pigs and wolves in rural areas, especially as it has spread widely at present.
